No. DmDeleteRecord calls MemHandleFree, which works even if the handle is
locked.
However, good form says you should always unlock a handle you've locked.
At some point we might having the debug ROMs give you a warning if you try
to free a locked handle, because this is often a source of memory
management bugs. (...when you later try to access the deleted/dangling
pointer.)
